BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 198,968, dated J' une6, 1893.

Application filed November 28, 1892. Serial No. 453,300. (No model.)

To aZZ whom it may concern:

'Be it known that we, ALBERT D. COOKE and ELIsHA D. SHAW, citizens ofthe United States, residing atthe city of Philadelphia, in

the county of Philadelphia and State of Penn-` out the intervention of arectangular framework resting upon slats and attached to the web;second, to construct the web holding devices for operation in suchmanner that the Web may be packed into a very small compass for storageor shipment and may be readily applied to the frame-work of a bedsteadwithout the employment of slats; and third, to provide compact andefficient mechanism for tightening or stretching the web wheneveritbecomes necessary or desirable so to do.

In our invention use is made of a web secured at one end to a rodattached to the framework of a bedstead and at the other.

end to a roller journaled to said frame-work and controlled by detenteand a ratchet-lever and ratchet-wheel.

Our invention consists in the improvements hereinafter fully describedand particularly pointed out in the claims.

The nature, objects and scope of our invention will be more fullyunderstood from the following description taken in connection with theaccompanying drawings forming part hereof; and in which Figure 1, is aperspective View of a bedstead showing a bed-bottom comprising a websecured to the frame-work of the bedstead by means of web holdingdevices embodying features of our invention. Fig. 2, is a detached sideelevational View drawn to an enlarged scale of the roller shown inFig. 1. Fig. 3, is

a perspective view of one of the sockets for supporting the rollerillustrated in Fig. 2, showing also a detent for preventing retrogrademotion thereof. Figs. 4L and 5, are respectively a front and a sideelevational view of the ratchet-lever shown in Fig. 1; and Fig. 6, is adetached plan view of a roller-having a single breadth of web securedthereto.

In the drawings a, is a web of any required texture that constitutes thebed-bottom and is attached directly to the frame-work bof a bedstead bymeans of web supporting and stretching devices hereinafter described andin such manner that Slat-bearers and slats are dispensed with, whereby aconsiderable saving in the expense with respect to the bottomsiseffected. This web a, may be made in two breadths a and a2, as shown inFig. 1, or in a single breadth as will be hereinafter described. One ofthe respective extremities of each of the breadths a and a2, ot' theweb, is attached to a""bar c, in any suitable manner as by clamping itby means of a Wedge-shaped liller fitted over the ends of the webs a anda?, and into a groove in the bar c. In the present instance the bar c,ismade in two parts and the ends of the breadths of the web are clampedand firmly held between them by means of screws c. Of course, rivets,hinges pr catches may be employed in lieu of the screws c', or, ifpreferred, thetwo parts of the bar c, Inay be tied together with cords,bands or the like. The bar c, is attached to one end of the bedsteadeither by 'fitting it into sockets secured to the side rails or posts,or as in the present instance, by means of hooks c2, connected with aspecial strip c3, suitably attached to the frame-work h, of thebedstead, and adapted to engage eyes fastened to the bar c. The otherends of the breadths a and a2, of the web a, are secured to a roller d,in any suitablemanner. In the present instance the roller d, is dividedlongitudinally into two parts and the ends of the breadths a and a2, areclamped between these parts by means of screws d. This roller d, isdivided transversely into two parts and these parts are pinned orotherwise secured to a union e, Figs. 2 and 6, that is provided with aratchet-wheel c', located inter- IOO mediate of seats e2. Theextremities of the roller d, are provided with gudgeons or pivots f,which are adapted to be dropped into sockets attached to the side railsor ostsV of the bedstead and with toothed wheels f2.

g, are detents pivotally attached to the sockets f', Fig. 3, andprovided with several teeth meshing with the toothed wheels f2, in orderto prevent retrograde movement of the roller d, due to the strain ortension of the web. These detents are provided with lugs g', by means ofwhich they may be readily lifted out of operative position whenever itbecomes necessary or desirable so to do.

The respective divisions of the roller d, Fig. 2, are of increasingdiameter from the ends toward the center thereof, in order to compensatefor the eXtra sagging that always occurs in the center portion of a webthat constitutes ka bed-bottom and is provided with reinforced orstiffened edges.

h, is a ratchet-lever preferably comprising a sleeve h', and a handleh2, adapted to vbe telescoped when not in use and provided with aset-screw h3, for clamping said parts in open or closed position. Thesleeve portion h', of this ratchet-lever h, is journaled as at h4, to apair of twopart collars h5, that are adapted to encircle the seats e2.

fi, is a pawl depending from the collars h5, into engagement with theratchet-wheel c', and provided with a lug t', by means of which it maybe thrown out of and into action.

In some vcases a single breadth of web is preferable to two breadthslocated side by side. In such cases the roller d, is of increasingdiameter from the ends toward the center, as shown in Fig. 6, in orderto compensate for any excessive sagging that may occur at the centerportion of the web,-and the web itself is divided for a short distanceas at a3, and reinforced as at a4, in order to accom modate theratchet-lever h. Y

The mode of operation of the hereinabove described mechanism is asfollowssThe bedbottom in a compact roll strapped upon the roller d, andwith the ratchet-lever h, either detached or simply turned down andWound up in the roll, is fitted into the socketsf. The straps are thenunbuckled and the vbar c, is secured to place at the opposite end of thebedstead in the manner above described. Under these circumstances theweb is very loose and must be stretched. This is accomplished bythrowing the detents g and pawl t', into action, turning theratchet-lever h, into the position illustrated by full lines in Fig. 1,and then reciprocating the ratchet-lever h, back and forth, thus causingthe pawl t', acting through the instrumentality of the ratchetwheel el',to rotate the roller d, and thus tighten or stretch the web. After theweb has been properly tightened the ratchet-lever h, may be telescopedand turned into the position illustrated by dotted lines in Fig. l, in

order to cause it to assume a position out of the way and `out of sight.v

It may be remarked that by the employment of the hereinabove describeddevices and arrangement of parts, We are enabled to dispense with slat.bearings, slats and heavy cumbersome framings for stretching andsupporting the web, and to provide a neat, light and comparativelyinexpensive bed-bottom which constitutes an integral part of thebedstead.

I'Iaving thus described the nature and objects of our invention, what weclaim as new, and desire to secure by Letters Patent, is`

l. In a bedstead, a web detachably secured at one end to the side railsor posts and at the other end to a divided roller provided with acentral ratchet-wheel and with end toothed Wheels and gudgeons orpivotsengaging sock ets, detents provided with a series of teeth adapted toengage with the end toothed wheels of said roller to prevent retrogrademovement thereof due to strain or tension of the web and said detentsprovided with means for the release thereof, and a telescoping leverstraddling said ratchet-wheel and provided with a pawl adapted to engagesaid ratchet-wheel, substantially as and for the purposes set forth.

2. In a bedstead, a two part bar provided with devices for clamping oneend of the web between the parts thereof, hooks and eyelets forconnecting said bar to the bedstead, a divided web tightening rollerprovided with end toothed wheels and pivots engaging sockets, notcheddetents adapted to engage the end toothed wheels of said rollers, aratchet-wheel centrally secured to said tightening-roller, and

a lever provided with a paWl straddling said ratchetewheel,substantially as and for the purposes set forth.

3. In a bedstead, a web tightening roller provided with a collar havinga sleeve adapted to be folded down onto the roller, a handle working insaid sleeve, and pawl-and-ratchet connections between the collarandroller, substantially as and for the purposes set forth.

4. A bedstead provided with a web detachably secured at one end to a barapplied to the side rails or posts thereof and at the other end to adivided roller havinga collar mounted thereon provided with a sleeveadapted to be folded down onto the roller, a handle workingtelescopically in said sleeve and pawland-ratchet connections 4betweenthe collar and roller, substantially as and for-the purposes set forth.

In testimony whereof we have hereunto set our signatures in the presenceof two subscribing witnesses.
